The δ(30)Si peak value discovered in middle Proterozoic chert and its implication for environmental variations in the ancient ocean
The silicon isotope composition of chert has recently been used to study the historic evolution of the global ocean. It has been suggested that Precambrian cherts have much higher δ(30)Si values than Phanerozoic cherts do and that the former show an increasing trend from 3.5 to 0.85 Ga, reflecting a...
